What characterizes an atypical squamous cell?

An atypical squamous cell is characterized by having abnormal morphology that may suggest the presence of neoplasia, indicating that there is a possibility of precancerous changes or cancer itself. In this context, "abnormal morphology" can include variations in size, shape, and structure of the cell when viewed under a microscope. These changes are significant as they provide vital information about a patient’s health status, particularly in relation to conditions like cervical dysplasia or carcinoma.

Recognizing and accurately identifying atypical squamous cells in cytology is crucial for early detection and intervention, which can ultimately improve patient outcomes. Differentiating these cells from normal morphology is a key aspect in the screening processes for various malignancies.

The other choices are less relevant in defining atypical squamous cells. A cell with normal morphology or a benign squamous cell does not exhibit the characteristics of atypical cells, as they would fall within the expected range of normal variations. Similarly, while inflammation may be associated with various cellular changes, including atypical cells in some cases, it does not define what makes a squamous cell atypical.
